Application filed January 18, 1907. Serial No. 352,945.

To all whom it may concern:

MAKER and ELIAS C. HOLLAND, citizensjof the United States, and residents of the city of Benton Harbor, in .the State of Michigan, have invented certain new and usefullmprovements in Temporary Binders; andwe do hereby declare the following to be a full and complete description of the same.

Our invention relates particularly to that class of temporary binders which have a varying holding capacity, and our invention resides in the special features'described herein, reference being had to the accompanying drawings. a y

In the drawings, Figure l'shows a perspec tive view of our binder. I Fig. 2 shows the binding edge of one. of our leaves. Fig. 3 shows a sectional view of our binder lock takenperpendicularlythrough the line of the binding posts of Fig. 1 Fig. 4 is a plan view of the bottom side of the binding cover of our binder. Fig. 5 is a detail showing the locking mechanism. F ig. 6 is a further detail of the same and Fig. 7 a detail of further construction of said binder.

More particularly described A, and A rep:

resent the binding bars of our binder and X,

and X, the covers of the binder attached to the said binding bars respectively.

, A represents the bottom bar of'ou-r binder,

to which the binding posts B B are rigidly attached and may be of any suitable-form or material. i,

A, represents the locking bar of our binder and is suitably perforatedto slide uponthe binding posts B B. The locking bar A, is. constructed as follows: A channeled bar a, is provided, fitted with a channel c withinwhich lies the lock mechanism of the/binder. A late (1 is designed to coverthe said channe a, being secured from the underside of the bar, a by the screws a'. channel orrecess a We place two leverarms C C lying opposed to each other and provided at their inner ends with slots 0 and formed at theirouter ends into hooks c 0 which hooks lie opposed to and are intended to engage with the binding posts BB. Midway of the lever arms they are slotted at c 0 through Specification of Letters Patent.

slots pass rivets d 01. which are at- Be it known that we, GEORGE A. SHOE-' tached at their opposite ends to the bar a and the platea respectively. Between the innerends of the lever arms C Cand cooperating with the'said arms, we provide a yoke Cfl'which is provided with lugs c c which engage the slots .0 c of the arms C C. Within the yoke C we provide an eccentric, one which. is rotatably secured to the; plate a by the screw 0, and which at its upper end'projects beyond the outer surface of the bar a,

and is fitted with a key head 0 It is designed that the rotation of the eccentric moves the yoke C laterally within the said lockinlgfbar A and thereby engages and disparts. i In order to prevent the complete revolution'of the eccentricand thereby permit in the locking movement the turning of the eccentric beyond the locking point, we provide a small stud c attached to the under side of the said'eccentric c, which stud moves within a semi-circular slot in the plate a as shown at'Eig. f4. 7

We provide a permanent and durable means of attachii'i gthe covers X and X to the binding bars AA", described as follows! Upon the bar a, we provide contiguous therewith and projecting forward beyond the for ward edge of said bar, the ears, E E E, which we perforate longitudinally. To these erforated ears we attach a perforated meta strip The covers of terial', arebuilt upon andaround these metal strips E the perforations c 6 serving to hold the binding materials in place. The finishing leather or other covering, H, is placed around and over coversX and X and the binding bars A and A as one piece, the hinges at the ears E, showing as in Fig, 1 of the drawings. I i

For the purpose of preventing the scratching or marring of desks or tables, we provide means of rotecting the same from the metal corners 0 the binding bars A and A by placing thereon raised corners of rubber or other resilient material, the detail of which rubber corner is shown at Fig. 7. We provide these corners in the following manner: An angle of metal is cut from the corner of the metal bar a, and the rubber piece D, cut to fit saidangle and project beyond the outer surface of the bar, is fitted upon said angle. It is held in place by a headed plug (1 thrust through said corners D, and engaged from below by a screw d, which passes through the metal bar A. U on the binding posts B B are placed the ba 1 caps b, b which are larger than the perforations of the locking bar A, through which the binding posts pass and will not ermit the removal of the locking bar A, rom the posts B B. The leaves therefore to be used in the binder must be so constructed that they may be inserted and removed without passing over the ends of the posts B B. In order to accomplish this we provide the leaves F, as shown at Fig. 2 and fit them with slotted perforations f f, whereby they may be passed around the binding posts B B for the purpose of insertion and removal from the binder.

What we claim as our invention is:

1. The combination with perforated leaves of a binding device comprising binder posts engaging said perforated leaves, covers, one of which is fixed to said posts and one is adapted to slide thereupon, and a lock at tached to said sliding cover consisting of a channel bar, a plate covering the said channel, lever arms opposed to each other lying within said channel and having engagement with said binder posts and means for actuating said lever arms consisting of an eccentricattached to said channel bar, a yoke engaging said eccentric and adapted to engage the inner ends of the said lever arms whereby the said lever arms may be moved laterally in the same direction to engage the said osts,

2. The combination with perforated leaves of a binding device comprising binder posts engaging said perforated leaves, covers, one Ofwhich is fixed to said posts and one is adapted to slide thereupon, and a lock forming the binding part of said sliding cover, consisting of a bar, a channel therein, a plate covering said channel, said bar and plate being'perforated to correspond with the position of said binder posts, lever arms lying within said channel, the outer ends of which are adapted to engage said binder-posts and the inner ends having cooperation with each other, elongated slots fixed in said lever arms, pins passing through said slots and fixed rigidly to said bar and said plate; a yoke adapted to engage the said leverarms and an eccentric fitted within said yoke whereby the same is adapted to be moved laterally within said channel.

3. The combination with perforated lemes of a binding device comprising llllltlvlfllfir lh engaging said perforated leaves, rovers, one of which is iii-Led to said posts and one is adapted to slide thereupon, and a lock forming the binding partof sad sliding cover, consisting of a bar, a channel therein, a plate adapted to cover said channel, said bar and plate being fitted with perforations corresponding in position with said l )inder posts, lever arms lying within said channel and. adapted to engage the said binder-posts, and means for moving said lever arms laterally within said channel, consisting of a yoke engaging the inner ends of said lever arms, and an eccentric lying within said yoke, and means for preventing complete revolution of said eccentric, consisting of a semi-circular slot cut in the face of said plate, and a stud fixed to the face of said eccentric and having engagement with said semi-circular slot.
